Title: Object incremental displacement coder - uses sliding cursor on spiral winding to generate square wave signals
Inventor: ILLINGER GUY
IPC: H03M1/00
Filed: 1975-10-09
Abstract: The coder has a moving element which moves with respect to a stationary part of the coder, which is a spiral winding wound on a support. Various moving systems may be used - either inductive, capacitive or opto-electronic. The inductive system uses a moving contact sliding over successive coils. The moving rubber contact (4) is displaced along the winding and establishes contact with one or two coils of the winding. The device then produces a square wave pulse dependent on the particular position adopted by the moving contact.

Title: Vincamine and (16)-epivincamine prepn. - from tabersonine salt by hydrogenating and oxidative rearrangement
IPC: C07D519/04
Filed: 1975-11-20
Abstract: Prepn. of vincamine (I) and 17-epivincamine (II) comprises forming an acid-addn. salt of (-)-tabersonine (III) and subjecting this to catalytic hydrogenation and oxidative rearrangement with an equimolar amt. of peroxide. Hydrogenation can precede or follow oxidative rearrangement. The resulting mixt. of (I) and (II) is sepd. by physical methods. N-blocking by salt formation prevents side reactions (e.g N-oxide formation) and allows polar solvents to be used. In an example, (III) HCl is hydrogenated with PtO2 in H2O and then treate with p-nitroperbenzoic acid.
Patent FR-2331955-A1 (FR)
Title: Cheese cleaning and washing machine with endless brush - ejects cheese from rest on three rotating brushes automatically
IPC: A01J27/00
Filed: 1975-11-18
Abstract: Machine has a pivoting bracket supporting three brushes. The angle of inclination of the bracket can be varied so that the cheese being treated rests with its flat face on one brush whilst its narrow edge contacts the other two. The first brush is in the form of a flat disc rotating in a plane parallel to the long axis of the bracket, and it is slightly eccentric to its shaft through which washing water is delivered. The two other brushes are located symmetrically beneath the first, on shafts at right angles to the long axis of the bracket, and a supply pipe sprays water on to the surface of one brush. Machine is of simple design and can be used for treating cheeses of different dias. and hardness without risk of damage. The effort exerted by the brushes, depending partly upon the wt. of the cheeses, can also be easily adjusted. A machine with a brush in the form of an endless belt is partic. suited to large size cheeses which are difficult to handle.

Title: Crude pellets for reduction in rotary furnace - produced from dust contg. iron mixed with carbon source and bentonite
IPC: C22B1/24
Filed: 1976-01-05
Abstract: dust (I) is mixed with a C-source (II) consisting of coke and/or coal comminuted to fine particles and contg. a large quantity of C having low volatility. Ratio of C no. in (I) + (II) mixt. to no. of 0-atoms bonded to Fe in (I) + (II) mixt. is 0.75-1.25. Mixt. (I) + (II) is mixed with 0.5-7 (0.8-3) wt. % (w.r.t. mixt.) of bentonite. Resulting mixt. is pelletised to form pellets having porosity 27-40%. Pellets are dried at a temp. such that C in pellets is not burned, pref. at 300 degrees C. Crude pellets can easily be reduced to metallised pellets having a high Fe content. Bentonite content and porosity >27% prevent the breaking of pellets on quick heating to 400 degrees C. Bentonite improves compressive strength of pellets.

Title: Self pumping safety tyre - with radial membrane and non return valve set tangentially to avoid centrifugal forces
IPC: B60C23/00
Filed: 1976-07-26
Abstract: The safety tyre is fitted to the wheel rim (13) as a tubeless type. It is fitted with an internal membrane (15) across the inside of the tyre and has a non return valve (16) behind the membrane when the wheel is running forwards. The valve thus pumps the tyre when it is deflated, with air let into the tyre every time the membrane section touches the road, and causes a negative pressure inside the section (14d) above the valve. When the tyre is inflated normally the valve is shut. The valve element (17) can be set tangentially so that it is unaffected by centrifugal forces. The system enablesa safety tyre to be driven over longer distances, even with large punctures.

Title: Casting flat horizontal ingots with good surfaces - where ingot moulds travel through a casting tunnel fed with a coolant
IPC: B22D9/00
Filed: 1976-12-03
Abstract: Flat horizontal steel ingots with a larger width than height are cast from a ladle into long, moving, horizontal moulds with an open top surface in a protective atmos. free from O2. After casting, the ingot is cooled in the mould by feeding a coolant, e.g. water or liq. N2 onto the top surface of the ingot. The coolant is pref. employed within 1-120, esp. 10-60 seconds after casting, esp. using (a) water within 30-60 second after casting, and for a period of 8-12 second; or (b) liq. N2 while the mould is still in the protective atmos. After cooling the top surface of the ingot, the mould is pref. rotated 180 degrees on its axis so any pores form in the middle and not on the surface of the ingot. The pref. plant uses an air-tight tunnel filled with inert gas, and with a conveyor carrying the moulds through the tunnel and under a tundish; a weighing machine is used to control the wt. of metal poured into each mould, and heaters are used to keep the top surface of the ingots in a plastic state after salification. Flat steel ingots are obtd. with an excellent surface quality and without segregation.

Title: Valve for closing end of pipe partic. after accidental breakage - is in two parts for fitting around pipe to avoid passage through fluid jet during fixing
IPC: E21B34/02
Filed: 1977-05-11
Abstract: A device for closing the end of a pipe consists of a valve in two parts which can be sepd. and which are on either side of a plane passing through the axis of an internal cylindrical surface of the valve which can be fitted round the outer surface of the pipe. The two parts can be tightened against one another on either side of the pipe. A plate is mounted so as to slide under the action of a screw mechanism and close the orifice of the valve. The device is for stopping the flow of a fluid escaping from the end of a pipe e.g. when the pipe has been accidentally broken. It is partic. adaptable to pipes of oil wells, but can be used in all industries in which fluids are conveyed in pipes. It allows rapid control of an escape at low or high press. and at all temps. without danger to the operators. It is installed without any of the components having to pass through the jet of fluid under press.

Title: Solar energy collector with water circulation - has peripheral frame with grooves accepting edges of constituent elements and joints, eliminating thermal bridging losses
Inventor: PAYMAL ANDRE
IPC: F24J2/04
Filed: 1977-08-01
Abstract: Solar energy collector with water circulation incorporates a peripheral frame which has the same section on all four sides. This section includes parallel grooves in which are engaged, with interposition of a thermally insulating and fluid-tight joint, the edges of a glass plate, a metal surface for absorbing radiation and a protective shell. The components fixing the collector on its support are housed in a groove in the section, independent of those which accept the edges of the constituents of the collector. Problems associated with losses of heat through thermal bridges between the internal hot parts of the absorber and the ambient atmos. and the collector support are avoided in a simple and economical way. Joints are needed only between the edges of the elements of the collector and the grooves in the section. A U-section joint can be used e.g. for the edge of the metal absorbant.
